AB  - Amphibian species that inhabit temporary ponds for reproduction maximize larval growth under favorable conditions and accelerate their development to undergo rapid metamorphosis under stressful conditions such as pond drying. Corticosterone controls development, metabolism, and growth, and has an invaluable role in anuran metamorphosis under stress conditions. In this study, we evaluated whether the whole-body corticosterone (CORT) level is related to drying conditions in species that cannot accelerate the developmental rate in response to pond drying. Specifically, we investigated the effects of different water levels in combination with exogenous CORT and corticosteroid synthesis inhibitor metyrapone (treatments: high water level, high water level with exogenous CORT, low water level, low water level with metyrapone) on the whole-body corticosterone (at prometamorphosis and metamorphic climax), life history and morphological traits at the metamorphic climax. We found that these conditions did not alter the whole-body content of CORT and the developmental rate in treatments, although low water levels and exogenous CORT in high water level negatively affected other life history traits and tail shape. Individuals from a high water level with exogenous CORT had the smallest body size and mass and changed tail shape at metamorphosis, while changes in life history traits did not affect the tail shape in the other treatments. Our findings indicate that the absence of developmental response (i.e. canalized development) in the timing of metamorphosis of B. variegata may be explained by a modification of endocrine regulation but further studies that would include closely related species are required.

AB  - Many amphibian species inhabit temporary aquatic habitats for reproduction to
maximize larval growth under favorable conditions but accelerate developmental rate
to rapidly undergo metamorphosis under stress conditions when high desiccation risk
exists. Corticosterone, one of the most important vertebrate stress hormone controls
development, metabolism, and skeletal growth and together with thyroid hormone
have a critical role in anuran metamorphosis under stress conditions. Here we
compare the hormonal variation of corticosterone (CORT) in the yellow-bellied toad
Bombina variegata tadpoles in response to different water levels (constant highcontrol, constant low, constant high+exogenous CORT) and the corticosterone
inhibitor- metyrapone (MET) (treatment constant low water level+MET). Also, we
investigated the effects of CORT and MET on life-history and morphological traits at
metamorphosis. We found that B. variegata tadpoles cannot accelerate the
developmental rate in response to pond drying. The constant low water level did not
alter whole-body content of CORT and it did not significantly differ from high water
level treatment with exogenous CORT. However, individuals from high water level with
exogenous CORT have prolonged development, the highest mortality rate, the smallest
body size and mass, and the widest but the shortest tails at metamorphosis. Constant
low water level with MET decreased the whole-body content of CORT and it was
significantly different between all groups, but it did not affect the developmental rate
and tail shape although these tadpoles have intermediate size and mass between high
water levels with exogenous CORT and control. We show that responsiveness to pond
drying of Bombina variegata and its short larval period is probably associated with
modified endocrine signaling pathway that control tadpole metamorphosis.
Constitutively high whole-body content of CORT which was unaltered by pond drying
leads us to conclusion that Bombina variegata development may be canalized but more
research is needed.
